WHAT ARE OPTICAL TRANSCEIVERS? An optical transceiver is also known as Fiber Optical Transceiver or Optical Module. A ‘Transceiver’ is made up of two words, transmitter’ and ‘receiver’ which means it can perform the function of both a transmitter and a receiver. 02
HOW OPTICAL TRANSCEIVERS WORK? A transceiver sends information as light, it utilizes a light source, for example, VSCEL, FP, and DFB laser, which is controlled by electronic devices, and to receive light pulses, for example, it utilizes a photodiode semiconductor. 03
WHAT ARE THE BASIC PARAMETERS OF OPTICAL TRANSCEIVERS? The creation of a product needs multi-channel discovery detection. There are a few parameters that are significant in the testing of anoptical transceiver. Just these parameters can make the optical module best for your application. 04
OUTPUT POWER Output power is used to determine the intensity of light received at the transmitting end and measured in dBm. This parameter seriously affects the transmission distance. 05
EXTINCTION RATIO This is another important parameter that checks the size ratio of the output power. It is inversely proportional to the optical power parameter, so when it is small the optical power will be large and when it is large optical power will be small. 06
RECEIVING SENSITIVITY It is the power at which the receiver of the optical transceiver can receive optical signals. It should be within the range of bit error rate (BER = 10-12), in dBm. 07
SWEDISH TELECOM OPTO OPERATING TEMPERATURE For Commercial it is 0~70 ℃ and for Industrial it is 40- 85℃ 08
